Unlike the thoroughly investigated melanocyte population in the hair follicle of the epidermis, the growth and differentiation requirements of the melanocytes in the eye, harderian gland and inner ear - the so-called non-cutaneous melanocytes - remain unclear. In this study, we investigated the in vitro and in vivo effects of the factors that regulate melanocyte development on the stem cells or...

Malignant melanoma is one of the most dangerous forms of cutaneous malignancies [1] . It is classified as cutaneous melanoma and non-cutaneous melanoma based on the location of the lesion. Ultraviolet (UV) radiation exposure is a predisposing factor for cutaneous melanoma, although in other forms such as mucous and anorectal malignant melanomas, ultraviolet radiation does not play a significant...
